We provide quick and easy online ordering of all types of LC Connectors Here are the detailed epoxy LC connector assembly and termination instructions for both single mode and multimode LC connectors. The steps are pretty generic and are applicable to most major brands’ LC connectors on the market, such as those from 3M, Seiko, Corning, Molex, AMP, etc. Here are the LC connector components before assembly. Here is the LC connector after assembly.   Step 1: Set Up the Heat Curing Oven a) Place oven on a level surface and away from combustibles. b) Connect the oven’s power cord

National Electrical Code 2008 covers the grounding or interruption of non-current-carrying metallic members of optical fiber cables. The grounding rules are defined for outside or inside of a building. The main rule is defined in NEC section 770.100 – Entrance Cable Grounding. Entrance Cable Grounding Grounding conductor needs to be insulated, made of copper (or other corrosion resistant material), and stranded or solid. The size must be no smaller than 14 AWG and having an ampacity equal or larger than the conductive elements of the cable assembly, but it doesn’t need to be larger than 6 AWG. It must be

Single mode optical connectors work with both 1310nm and 1550nm, but the coupling loss is very different between these two wavelengths. The loss in decibels at a connector is about 7% greater at 1310nm than at 1550nm, based on measured data. And some equations were developed which is pretty consistent with actual measurement result. The conclusion is simple: the loss in a connector is slightly larger at shorter wavelengths. The coupling loss calculation equations involve more than wavelength, mode field diameter and refractive index also plays important role which makes the loss calculation a much more complex function of wavelength.

Up until now, the most common curing agent used in fiber optic connector termination is a heat-cured epoxy. The epoxy is injected into the connector, fiber is pushed through the ferrule and then the connector is placed into a heat oven, where heat causes the curing process. Heat-cured epoxies are relative inert, and can be used with plastic, metal and ceramic fiber connectors. But anaerobic adhesives as a curing agent in fiber connector termination have become pretty popular today, especially in field installation and terminations, because of the rapid curing time. Anaerobic adhesives are made of two parts, an adhesive

In addition to transmission loss, we also have to consider the back-reflection that occurs at the fiber optic connector interface. Back reflection always happen when there is a change of refractive index. The amount of light that is reflected back can cause undesirable system and network effects, thus it must be minimized. With today’s 10Gbit/s, 40Gbit/s and even 100Gbit/s high date rates, video over fiber links with lots of connections, connection back-reflection has become very critical. In those undesirable effects, increased noise if one of them. This noise is analogous to multipath interference noise of radio waves in the atmosphere.
